📖 Biblical Definition
The Sign of Jonah is the only sign Christ promised to the unbelieving generation that demanded one. "An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas: For as Jonas was three days and three nights in the whale’s belly; so shall the Son of man be three days and three nights in the heart of the earth" (Matthew 12:39-40; cf. 16:4; Luke 11:29-30). The sign is His burial and resurrection. The reluctant prophet swallowed by the fish and disgorged alive on Nineveh’s coast typifies the willing Christ swallowed by death and risen on the third day. The unbelieving generation can have no sign greater than that — and no sign smaller than that.
📜 Webster 1828 Definition
(Composite.) The sign Christ promised to the demanding generation: His own death and resurrection, prefigured by Jonah's three days in the fish.

Recorded in Matthew 12:39-41 and Luke 11:29-32. The sign has two halves: Jonah's three days in the great fish (the resurrection foreshadow) and the men of Nineveh's repentance (the judgment standard).
Christ doubles the application: He is greater than Jonah; the Ninevites who repented at Jonah's preaching will rise in judgment against the generation that refused to repent at His.
📖 Key Scripture
Matthew 12:39 — "An evil and adulterous generation seeketh after a sign; and there shall no sign be given to it, but the sign of the prophet Jonas."
Matthew 12:40 — "For as Jonas was three days and three nights in the whale's belly; so shall the Son of man be three days and three nights in the heart of the earth."
Matthew 12:41 — "The men of Nineveh shall rise in judgment with this generation, and shall condemn it: because they repented at the preaching of Jonas; and, behold, a greater than Jonas is here."
Jonah 1:17 — "Now the LORD had prepared a great fish to swallow up Jonah. And Jonah was in the belly of the fish three days and three nights."
⚠️ Modern Corruption
Modern Christianity often retreats to debating Jonah's historicity; Christ stakes His own resurrection on Jonah's three days as fact.

Christ uses Jonah's experience as the type of His own. If Jonah is parable, Christ's argument falters; He is comparing one literal three-day descent to another. The two stand or fall together in His logic.
And the Ninevites are real witnesses at the Last Judgment, by Christ's own statement. Their repentance becomes a standard against which the present generation is measured. The recovery of the Sign of Jonah recovers both halves: real prophet, real type, real resurrection, real judgment.
🔗 Greek & Hebrew Roots
Greek sēmeion (sign) plus the prophet's name.

Greek sēmeion — sign, miracle, attesting indication.
Note: Hebrew Yonah means ‘dove’; the prophet's name preserves an irony in light of his bitter complaint at Nineveh's repentance.
Usage
